TalkPHP - So..I was bored...and was working with jQuery

When I thought why not make a jQuery-esk look a like now that we have the __invoke method. Libraries by default can be in the /Libraries directory relative to the Worker file. Or you can specify the library directory.

Note: There really isn't any legitimate use for this btw. It's just for fun.

Use:

php Code:

_('database')->query('select * from foo');
$_('database')->query('select * from foo');

Class:

php Code:

<?php

class Worker
{
    
    private $library;
    private $libraryDirectory;
    private static $instanceOfSelf;
        
        public static function getInstance()
        {
            if( !$instanceOfSelf instanceof Worker )
                self::$instanceOfSelf = new Worker;
                
            return self::$instanceOfSelf;
        }
        
        public function __invoke( $lib )
        {
            if( !array_key_exists($lib, $this->library) )
                $this->__loadLibrary($lib);
                
            return $this->library[ strtolower($lib) ];
                 
        }
        
        private function __construct($dir = null)
        {
            $this->library = array();
            $this->libraryDirectory = !is_dir($dir) ? $dir : dirname(__FILE__) . '/Libraries/';
        }
        
        private function __loadLibrary($library)
        {
            $libraryToLoad = $this->libraryDirectory . '/Lib_' . $library . '.php';
            if( !file_exists($libraryToLoad) )  
                throw new Exception('Library does not exists');
                
            require_once $libraryToLoad;
            $this->library[strtolower($library)] = new {'Lib_' . $library};
        }
        
}

$_ = Worker::getInstance();
function _( $func ){ global $_; return $_($func); }

Alternatively if you don't want the $_ global..

php Code:

function _($func)
{
    static $worker;
    if( !$worker instanceof Worker )
        $worker = Worker::getInstance();
    return $worker($func);
}
